For the construction or renovation of facilities, particularly in the chemical or petrochemical industry, complex piping systems often need to be created. The layout of the piping systems in space requires a high level of planning effort and skill in practical implementation. This is the area of expertise for the piping technician. Standardized pipes and fittings, which can be obtained through trade, as well as custom fittings that the technician must create themselves, are used. The practical manual for the piping technician contains information on the required dimensions and lengths, as well as how custom fittings can be manufactured. Numerous illustrated and easily understandable calculation examples and tables with dimensions and lengths of pipes and fittings provide the technician with concrete and quick assistance for calculations and production in their daily work.
